4 IMO-R21 EN 3. INSTALLATION 3.1 General Remove the protective packaging and flow port protectors and check that the valve is clean inside. Clean valve if necessary. Flush the tank car carefully before installing the valve. Foreign objects, such as sand or pieces of welding electrodes, will damage the ball and seats. Read and follow all WARNINGS! 3.4 Commissioning Ensure that there is no dirt or foreign objects left inside the valve or tank car. Flush the tank car carefully. Make sure that the valve is fully open when flushing. Ensure that all nuts and fittings are properly fastened. GOOD PRACTICE DICTATES THAT ONCE INSTALLED, BUT PRIOR TO FIRST USE, THE VALVE IS LEAK TESTED IN PLACE TO ASSURE LEAKTIGHTNESS HAS NOT BEEN COMPROMISED BY THE INSTALLATION PROCESS. INSTALLATION ACTIONS THAT CAN CAUSE LEAKAGE INCLUDE, BUT ARE NOT LIMITED TO; WRENCHING, SOLDERING, WELDING AND/OR HOISTING. SEE SECTION 4.5 SERIES 7RRR, 7RRT AND 7RRU VALVES ARE DESIGNED FOR MANUAL USE ONLY AND ARE NOT INTENDED FOR AUTOMATION! DO NOT FABRICATE OR ADD ON ANY TYPE OF AUTOMATING ACCESSORY. The Jamesbury Series 7RRR, 7RRT and 7RRU are an end entry design with an internal insert. The insert contains a hex drive which can be identified by looking into the end of the valve before installation. 3.2 Handles If the Series 7RRR, 7RRT or 7RRU valve handle (17) has to be removed for any reason, the handle must be remounted with the handle as shown in Figure 8 or 9. FAILURE TO PROPERLY MOUNT THE HANDLE MAY RESULT IN IMPROPER VALVE OPERATION, DAMAGE OR PERSONAL INJURY. 3.3 Installing on tank car THE VALVE SHOULD BE TIGHTENED BETWEEN FLANGES USING APPROPRIATE GASKETS AND FASTENERS COMPATIBLE WITH THE APPLICATION, AND IN COMPLIANCE WITH APPLICABLE PIPING CODES AND STANDARDS. CENTER THE FLANGE GASKETS CAREFULLY WHEN FITTING THE VALVE BETWEEN FLANGES. DO NOT ATTEMPT TO CORRECT MISALIGNMENT BY MEANS OF FLANGE BOLTING! The valve may be installed in any position and offers tightness in both directions. It is recommended, however, that the valve be installed with the insert (2) towards the tank car. Refer to the Section 4, MAINTENANCE for stem seal adjustment. If there is weepage past the stem seals upon installation, it means the valve may have been subject to wide temperature variations in shipment. Leak-tight performance will be restored by a simple stem seal adjustment described in the MAINTENANCE section. 4. MAINTENANCE 4.1 General Good operating procedure requires periodic observation to ensure that the valve is functioning well. The frequency of observation will depend on the application. Routine maintenance consists of tightening the bonnet cap screws (item 29 in Figure 8 or 9) periodically to compensate for stem seal wear. More frequent observation is recommended under extreme operating conditions. Overhaul maintenance consists of replacing seats and seals. A standard repair kit consisting of these parts may be obtained through your authorized Metso Distributor. NOTE: Repair kits include stem bearings (13), secondary stem seal (7), seats (5), body seal (6) and stem seal (8). Refer to the Repair Kit chart (see Table 3). FOR YOUR SAFETY IT IS IMPORTANT THE FOLLOWING PRECAUTIONS BE TAKEN PRIOR TO INSTALLATION, SERVICING OR REMOVAL OF THE VALVE FROM THE TANK CAR OR BEFORE ANY DISASSEMBLY: 1. WEAR ANY PROTECTIVE CLOTHING OR EQUIPMENT NORMALLY REQUIRED WHEN WORKING WITH THE FLUID INVOLVED. 2. DEPRESSURIZE THE TANK CAR AND CYCLE THE VALVE AS FOLLOWS: A. PLACE THE VALVE IN THE OPEN POSITION AND DRAIN THE TANK CAR. B. CYCLE THE VALVE TO RELIEVE RESIDUAL PRESSURE IN THE BODY CAVITY BEFORE REMOVAL FROM THE TANK CAR. C. AFTER REMOVAL AND BEFORE ANY DISASSEMBLY, CYCLE THE VALVE AGAIN SEVERAL TIMES. 3. THESE VALVES ARE SUITABLE FOR A WIDE VARIETY OF FLUIDS AND GASES. BE CERTAIN THAT THE VALVE MATERIALS SELECTED ARE SUITABLE FOR THE APPLICATION.

Holding the stem in place from the inside, install the stem seal (8) and the compression plate (20) over the end of the stem protruding out of the body stem bore as shown in Figure 8 or 9. 8. Place the disc springs (31) on the cap screws (29). Disc spring orientation shall be as shown in Figure 8 and 9. Insert cap scews (29) with springs into body and tighten finger-tight. 9. While pressing the stem (4) outward from inside the body, tighten the cap screws (29), apply torque evenly, alternating between the two nuts so that the compression plate will be parallel with the valve body. Rotate the stem gently to assure proper seating. 10. Tighten the cap screws (29) to the torque provided in (Table 2) (Hex head cap screw (29) torque). 11. Make sure there is no dirt and grit in the insert (2) threads. Apply a lubricant compatible with the flowing media to the threads and screw the insert (2) into the body (1) by hand until it is fully seated. Mark the position as shown in (Figure 6). Counting the number of turns, remove the insert. 3. Clamp the valve body (1) securely in a vise in the vertical position with the insert end up, taking care not to damage any valve sealing surfaces. 4. Place one valve seat (5) sidewise into the body cavity (1) to just below the stem hole and tilt it into place so that the proper face will come in contact with the ball (3) (see Figure 5). Figure 6 12. Align the stem (5) to the ball slot. Insert the ball (3) rotating it onto the stem (4) in the closed position. If necessary turn the stem blade to align with the ball slot. Figure 5 Seats should be in this position at Assembly. 5. Place the stem bearings (13) and secondary stem seal (7) on the stem (4) shown in Figure 8 or 9. 6. Insert the stem (4) with the bearings into the valve body and through the stem bore in the body, as shown in (Figure 2, 3 or 4). Press it gently up into the stem bore until resistance is felt from the lower stem bearing. Be careful not to scratch or damage the seals. 13. Insert the second seat (7) with the seat sealing surface towards the ball. (See Figure 5). 14. Insert the body seal (6) onto the insert (2). 15. Make sure there is no dirt and grit in the insert (2) threads. Using a thread lubricant compatible with the media, screw the insert (2) into the body (1) and tighten the insert. Insert must be tightened the same number of turns as in step 11, insuring that the marks are either lined up or insert mark is +/ 1/8 (Dimension A) either side of the body mark, as shown in Figure 7.

IMO-R21 EN 7 5. REPAIR KITS We recommend that valves be directed to our service center for maintenance. The service centers are equipped to provide rapid turnaround at reasonable cost and offer new valve warranty with all reconditioned valves. Standard Repair Kits (Table 3) include seats, seals, and stem bearings. 6. SERVICE/SPARE PARTS For further information or assistance on repair kits and spare parts visit our website at www.metso.com/valves. Figure 7 16. Install handle (17), lockwasher (19) on the stem (4), matching the flats on the stem and handle. The handle should be in the orientation as shown in Figure 2, 3 or 4 in the closed position. Thread handle nut (16) onto the stem and tighten per Table 2. 17. Cycle the valve slowly with a gentle back and forth motion to build gradually to the full quarter turn. A fast turning motion at this point may cut the seats before they have a chance to form the proper seal.
